Thin‐layer chromatography combined with surface‐enhanced Raman scattering for rapid detection of benzidine and 4‐aminobiphenyl in migration from food contact materials based on gold nanoparticle doped metal‐organic framework

In this work, a rapid and sensitive thin‐layer chromatography combined with surface‐enhanced Raman spectroscopy method was established for rapid detection of benzidine and 4‐aminobiphenyl in migration from food contact materials based on Au nanoparticle doped metal‐organic framework. Benzidine and 4‐aminobiphenyl were firstly separated by thin‐layer chromatography to solve the limitation of their overlapping Raman peaks. Then the target...
